Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention accepts a call from a caller irrespective of the communication status of the base station, and transmits the received call data to the base station without fail, and is flexible even when traffic increases or decreases. The present invention relates to a pager message storage system that can respond.

[0002]

2. Description of the Related Art A description will be given, with reference to FIG. 5, of a conventional pager call between a pager exchange and a base station. FIG. 5 is a diagram illustrating a conventional system configuration. It has a base station 10 that calls a pager in response to a transmitted call instruction, and a memory unit 28 that temporarily stores call data transmitted from the caller side. It is determined whether or not a call from the caller is accepted depending on the situation described above. If it becomes impossible to perform transmission to the base station 10 after the acceptance, a call is sent from the pager exchange 30 which stores the call data in the memory unit 28. It is configured.

[0003] An example of a conventional message information transmission system is described in Japanese Patent Application Laid-Open No. 63-198460. The voice storage system described in this publication registers the telephone number of the pager carried by the absence registered subscriber and calls the pager carried by the subscriber when the message information is stored in the voice storage device, By notifying the storage of the message information, the subscriber can acquire the message information without delay.

[0004]

However, in the conventional pager call, although the pager call is asynchronous and one-way data communication, the reception from the caller is limited to the situation on the base station side. Will depend on you. In addition, since the paging switch is designed to take into account restrictions on radio waves and assume that the transmission of call data to the base station will be abnormally concentrated, regulations and accumulation in the switch, and in some cases call Sometimes it was unavoidable to destroy the data. Furthermore, since the traffic differs depending on the area, a pager exchange / base station must be constructed according to the traffic.

An object of the present invention is to enable a call from a caller to be accepted to the utmost limit, and to further reliably transmit the received call data to a base station, and to flexibly cope with an increase or decrease in traffic. A message storage system is provided.

[0006]

According to the present invention, there is provided a message storage system comprising: a base station for calling a terminal device by calling data including a call instruction of a calling party and a message to a called party; A pager exchange that receives call data and transmits the call data to the called party regardless of any communication conditions of the base station, and receives the call data transmitted from the pager exchange, and A message storage system for analyzing paging data, storing the analyzed paging data, and controlling transmission of the stored paging data to the base station.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is intended to expand the acceptance procedure by storing transmission messages in a system different from the exchange when transmitting data from the pager exchange to the base station when a pager is called. And that the call can be performed more reliably.

The configuration of an embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a block diagram showing the configuration of a pager call message storage system according to the present invention. FIG. 2 is a block diagram showing the configuration of the message storage system of the present invention. A base station 10 that calls a pager according to the transmitted call instruction;
A pager 12 for receiving a message by a call from a caller, a pager exchange 14 for accepting a call from a caller and transmitting call data regardless of the situation on the base station 10 side, Receives call data and loads the call data into its own large memory,
And a message storage system 16 that controls transmission to the base station 10.

The message storage system 16 receives the call data from the pager exchange 14 as shown in FIG. 2, analyzes the contents and stores the call data, and the reception analyzer 18 receives the call data. A storage device 20 that classifies and stores call data by type, and a base station 10
, And fetches a message for each type stored in the storage device 20, transmits the message to the base station 10, accepts a response from the base station 10, occurrence of a failure, and the like, and constantly checks the status of the base station 10 side. A call control unit 22 that recognizes and regulates transmission and controls abnormal congestion.

Thus, in the present invention, the base station 10
Is not performed on the pager exchange 14 side, the call from the caller can be accepted regardless of the situation of the base station 10, and the exchange 10 is not a small-capacity storage memory. By using the large capacity storage medium of the message storage system 16, intensive calls within a single time can be handled.

The configuration of the embodiment has been described in detail above.
The call data from the pager exchange, as well as the data transmitted to the base station, the response from the base station, the occurrence of a failure of the base station is well known to those skilled in the art,
Further, since it is not directly related to the present invention, its detailed configuration is omitted. In the above embodiment, an external storage device may be used as the storage device.

Next, the operation of the embodiment of the present invention will be described in detail with reference to FIG. FIG. 3 is a diagram showing the flow of call data according to the present invention. When the call data from the pager exchange 14 is given to the reception analysis unit 18, the reception analysis unit 18
Analyzes call data, assigns call priorities, performs classification by necessity / unnecessity of reply from the base station 10, and stores the call data in the respective storage devices b1, b2, b3,... . The call control unit 22 extracts call data from the storage devices b1, b2, b3,... In a priority order, and stops transmission or transmits data that requires a reply depending on the situation of the base station 10. It performs control according to the base station 10 side, such as waiting for the next transmission.

Next, another embodiment of the present invention will be described in detail with reference to FIG. FIG. 4 is a diagram showing another embodiment of the present invention. A storage device 20 constituted by an external storage device for storing call data; a main processor 24 for receiving call data originating from a calling side and storing the call data in the storage device 20 as needed; At any time,
It comprises a pager exchange 26 having a call control device 22 for transmitting to the base station 10 and communicating with the base station 10 and recognizing the situation on the base station 10 side.

As described above, in the present embodiment, the storage device 2
The message storage system itself can be made a part of the pager switching station 26 by using 0 as a dedicated processor for storing the call data and the call control device as a dedicated processor.

Further, the message storage system does not need to be paired with the pager exchange 26 or the base station 10, and a plurality of pager exchanges 26 or a plurality of base stations 10 can be combined into one message storage system. Aggregation is also possible.

[0016]

The message storage system of the present invention does not control the call data in the exchange, so that the call can be accepted at any time without depending on the situation of the base station. Also,
Since call data can be stored in a large capacity instead of a small capacity memory in the exchange, it is possible to cope with a concentrated call within a single time or a concentrated call to the same subscriber. Further, since the storage device is a dedicated memory for storing the call data, the storage device can be increased or decreased according to the traffic of the pager exchange and the base station.
